Title: Use of c02/steam to enhance steam floods in horizontal wellbores
Inventor: JENNINGS ALFRED R JR
IPC: E21B43/30
Filed: 1990-07-13
Abstract: A method to enhance steam flooding where at least two horizontal wellbores are utilized. Carbon dioxide is injected into a lower perforated horizontal wellbore. Once sufficient carbon dioxide has been injected into the formation, steam is injected through the lower horizontal wellbore. The steam displaces the carbon dioxide into the formation where it contacts and mixes with hydrocarbonaceous fluids. Steam causes the carbon dioxide to expand, thereby providing for a better sweep of the formation. Steam injection is ceased and liquid carbon dioxide injection again is commenced. Afterwards, steam is injected again into the formation. This sequence is continued until it becomes uneconomical to produce hydrocarbonaceous fluids from an upper horizontal wellbore. Hydrocarbon displacement efficiencies are enhanced when hydrocarbons are produced into the upper horizontal wellbore due to viscosity and density differences.

Abstract: A CONTROL CIRCUIT FOR A SOLID STATE TELEPHONE LINE     CIRCUIT                           ABSTRACT    A control circuit for a solid state line circuit is disclosed that includes, in combination, a logic interface circuit connected to a central controller.  The logic interface circuit receives and stores digital data representing commands from the central controller and transmits status signals from the control circuit to the central controller.  A DC loop control circuit provides loop control voltage to the interface circuit which adjusts the loop current fed to a subscriber loop.  A loop sense comparator receives a representation of the subscriber loop voltage and compares the loop voltage to a threshold.  When the threshold is exceeded, the loop sense comparator transmits to the logic interface a status signal.  A ring trip circuit monitors the subscriber loop and transmits to the logic interface a status signal representing an interruption in ringing current applied to the subscriber loop.  An AC summing amplifier, amplifies voice signals transmitted on the subscriber loop and subtracts from the transmit voice signals, a receive voice component.  A switched capacitor filter, under control of the logic interface, provides either loaded or non-loaded network line balance operation.  The switched capacitor filter also receives a receive voice signal which it is uses to generate the subtraction signal used by the AC summing amplifier.

Title: Powder coating method for metallic surfaces
Inventor: BOHNACKER ULRICH
IPC: B05D1/14
Filed: 1991-09-19
Abstract: In electrostatic powder coating, the starting materials used are metal surfaces which are furnished with an oil film for protection against corrosion during storage and transport. The polymer powder is applied to the surface without removing the oil film. The powder layer is then melted in an oven and is finally cured by cooling. The heat applied by the oven should be sufficient to volatilise the oil. An oil is preferably used which remains stable or resistant during the heating process as long as it remains on the workpiece surface. This includes the possibility that individual components or the entire oil diffuse through the powder layer and evaporate during the heating-up process, or alternatively that part or all of the oil quantity remains on the workpiece during the heating process and mixes with the powder layer. In both cases, the quality of the plastic coating is not adversely affected by the oil film.
